Boundary Distance

Сформулирована и детализирована методика оценивания граничной дальности береговых ОВЧ радиостанций в направлении Берег-Судно, которая основана на зависимостях напряженности поля, полученных эмпирическим путем. Определены численные значения граничной дальности ОВЧ радиосвязи применительно к типовому судовому радиооборудованию и шумовой обстановке вблизи судовой антенны. Проведена оценка максимальных допусков определения граничной дальности ОВЧ радиосвязи. The procedure for estimating the boundary distance of the shore VHF radio stations in the shore-to-ship direction, which is based on the dependences of the electromagnetic field strength obtained empirically, has been formulated and detailed. Numerical values of the boundary distance of VHF radio communication in relation to typical ship radio equipment and the noise environment near the ship's antenna are determined. The estimation of the maximum tolerances for determining the boundary distance of VHF radio communication is carried out.

Instrumental Methods

В работе рассмотрены такие характеристики судового ОВЧ радиоканала, как напряженность поля полезного сигнала и ЭДС полезного сигнала на входе радиоприемного устройства (РПУ),которые являются функциями от отношения сигнал/шум на выходе (входе)РПУ. Введено понятие фактической чувствительности РПУ. Определены количественные значения анализируемых характеристик применительно к типовому судовому радиооборудованию и шумовой обстановке вблизи судовой антенны. The article considers such characteristics of the shipboard VHF radio channel as the electromagnetic field strength of the useful signal and the EMF of the useful signal at the input of the receiver, which are functions of the signal-to-noise ratio at the output (input) of the receiver. The concept of the actual sensitivity of the receiver is introduced. The quantitative values of the analyzed characteristics are determined in relation to the typical ship radio equipment and the noise environment near the ship antenna.

Increasingly, induction heaters are being widely applied to the energy-saving light industrial equipment. But their electromagnetic radiation’s impact on the environment can’t be ignored. In the paper, several medium frequency induction heaters had been studied under different experimental conditions using E61 electromagnetic field strength analyzer, and as its supplement, the racetrack-coils induction heater had been simulated using ANSYS. According to ICNIRP guidelines, the results show that their radiation is generally in critical state, and magnetic field strength is superstandard in some areas. And countermeasures to the problems are advised.
